Handlers
Handlers (sometimes called “callbacks”) are sort of like options, but they are functions that get called whenever something special happens. In the following example, an alert box will appear whenever the user clicks on a day:
var calendar = new Calendar(calendarEl, {
dateClick: function() {
alert('a day has been clicked!');
}
});
Dynamically adding Handlers
You can attach handlers after the calendar initializes using the on and off methods.
The below example dynamically binds a dateClick handler.
calendar.on('dateClick', function(info) {
console.log('clicked on ' + info.dateStr);
});
The API for on / off are very similar to Backbone’s on / off.
